This would be tough to implement.

You are charged with a timeout in the NFL if you challenge and lose, get the TO back if you win. Maybe they could do something similiar.

Still is not going to solve the problem.

They need to get rid of all the old beefs and grudges between refs/players and coaches. Get rid of the Superstar calls, home cooking, 0 tolerance rule. Get rid of all the refs who have short fuses.

If they approach reffing from a completly unbiased standpoint with level headed and fair officials then all the calls will balance out in the end and we will get to see some pretty good ball. Also get some stars that can compete better in the International games.
